对３４例粘膜相关淋巴组织（ＭＡＬＴ）起源的粘膜相关淋巴瘤（ＭＡＬ）病理组织学特征进行分析结果表明，瘤组织主要由滤泡中心样细胞（ＣＣＬ细胞）构成，可见嗜上皮性、浆细胞样分化及绣毯样图象等特征；转移至淋巴结时主要累及淋巴窦，而淋巴结结构常存在结果提示，ＭＡＬ组织学上是以小Ｂ细胞为主的淋巴瘤，可转化成快速进展行为的高度恶性大细胞性淋巴瘤ＭＡＬＴ的器官中，ＣＣＬ细胞弥漫性浸润是诊断ＭＡＬ的主要依据，结合淋巴上皮病损，浆细胞样分化及绣毯状结构将有助于与易混淆的低分化癌或未分化癌、淋巴组织反应性增生等鉴别
The histopathological features of mucosa-associated lymphoma (MAL) originated from 34 cases of mucosa-associated lymphoid tissue (MALT) were analyzed. The results showed that the tumor tissue was mainly composed of central follicular-like cells (CCL cells), and epithelial and pulpy were seen. Features such as cell-like differentiation and embroidered carpet-like images; metastasis to lymph nodes mainly involve lymphatic sinuses, and lymph node structure is often present. Results suggest that MALs are histologically small B-cell lymphomas, which can be transformed into rapid progress. In patients with highly malignant large cell lymphomas and/or MALT-like behaviors, diffuse infiltration of CCL cells is the main basis for diagnosing MAL. In combination with lymphoepithelial lesions, plasma cell-like differentiation and embroidered carpet structures will contribute to confusing Poorly differentiated or undifferentiated carcinoma, lymphoid tissue reactive hyperplasia, etc.
